Specification ofLetters Patent.

Patented Oct. 8, 1912.

Application filed September 6, 1910. Serial No. 580,467.

Mv invention relates particularly to folding goarts; and my prnnary ob cct 1s to provide improved mechanism for automat1-- ally folding the seat-back of such a structure in the operation of folding the go-cart.

The improved backfolding mechanism, while capable of automatically folding and unfolding the back with relation to the salt in the operation of folding and unfolding the superstructure of the cart, 1s nevertheless adapted to permit the back to be ad justed to either the standing positlon, a half-reclining position, or a full reclining position.

The invention is illustrated in the preferred embodiment in the accompanying drawings, in which- Figure 1 represents a broken slde elevational View of a folding go-cart embodying my invention; Fig. 2, a broken side elevationa] View of the same, showing the struc ture in the partially collapsed position; F 1g. 3, a broken longitudinal section, the section being taken as indicated at line 3 of Fig. 4; Fig. 4, a broken transverse section taken as indicated at line 4 of Fig. 1; F 5, a broken sectional view taken as indicated at line 5 of Fig. 1 and showing portions ofthe structurelocking mechanism and releasing means as sociated therewith; and Fig. (3, a section taken as indicated at line 6 of Fig.

Tn the construction illustrated, A represents a running-gear f mm; B, wheel-forks, or wheel-supports, connected by pivots l to fixedly secured brackets 2 carried by the side members of the running gear frame, said wheel-supports being adapted to fold in 'ardly in pairs transversely beneath the running-gear frame; C, a handle having its side members connected at their lower ends by pivots 3 to the rear portions of the sidemembers of the running-gear frame; C, arms pivotally connected at their rear ends with the side-members of the handle and pivotally joined at their front ends to the upper ends of arms, or links, C, which are joined, by pivots 4, to the running-gear frame; (7 a U-shaped member which has its upturned arms rigidly connected with the links, or members, (1*, and which has a cross-member, or web, 5 with which is connectcd mechanism (3, which serves to automatically fold and unfold the wheels with relation to the rnnninggear frame when the superstructure is folded and unfolded; D, a seat which is mounted. preferably resiliently, on the running-gear frame; I), a back pivotally connected with the seat; I), backfolding and adjusting mechanism connected with the seat, and also connected with the folding snpcrstructiare of the cartg-F, locking mechanism for the go-cart structure; and F. releasing means associated with said locking mechanism.

The running-gen r frame A may be of any suitable construction. As shown, it is composed of side-mcmbcrs 7 formed integrally with a front cross-member 8; and cross-bars S) and 10 connecting the side-members 7 in the vicinity of the front and rear wheel-supports, respectively. The fixedlysecured bracket-mcmbers :2 which are attached to the side-members 7 of the running-gear frame are strengthened by means of braces 11 which connect them with the cross-miembers S) and '10.

The wheel-supports, or heel-forks, may be of any desired construction. They are usually connected together in pairs at the opposite sides of the go-cart and adapted to fold transversely inwardly beneath the running-gear frame.

The handle C may be of any approved construction. It usually comprises side-bars and a cross-round (not shown) connecting the upper ends of the side-bars. The manner in which the handle and other portions of the superstructure fold with relation to the running-gear frame and in such folding operation operate to automatically fold the wheels beneath the running-gear frame through the medium of the mechanism (3. is fully explained in my pending application No, 546,926. filed March .2, 1910. in its folding operatitm, the U-shapcd member C swings reaxwvardly, as illustrated in Fig. 2.

The manner in which the seat D is resiliently mounted on the running-gear frame is explained and claimed in my appli ation No. 580,468, filed September (3, 1910. In order that the present invention may be fully understood, however, it is desirable that the manner of mounting the seat shall wardly and being 'olfset downwardly edgewise so as to extend beneath the cross-bar 9 of the running-gear frame, the front ends of the levers being provided with slots 18 which receive headed studs 19 carried by the front portions of the side-members 7 of the running-gear frame, said studs projecting inwardly from said side-members. Mounted on the intermediate portions of the supporting levers 17 is a U-shaped seat-support 20 whose downturned arms are secured by rivets 21 to said levers l7, and whose Web or cross-member supports the front portion of the seat.

It will be understood from the foregoing that the springs 13 support the rear portion of the seat, that the levers 17 are carried partially by the springs 13 and partially by the front portion of the running-gear frame, and that the front portion of the seat is mounted on the levers 17 through the medium of the member 20. Thus, the seat is supported in a manner to afford the fullest spring action, or resiliency, and this result is accomplished without interfering with the folding action of the go-cart structure.

The back D is equipped with straps, or hinge-members, 22 which are connected with the pivots 16 carried by the arms 15 rising from the rear portion of the seat. The mechanism E which serves to adjust the back in any of the three positions desired,

and also to automatically fold the back in the operation of folding the go-cart structure, comprises a pair of levers 23 connected by pivots 24 with the seat-supporting levers 17 some distance in front of the pivots 16; links 25 connected at their rear ends, by-pivots 26, with the lower ends of the levers 23 and joined at their front ends by pin-and-slot connections 27 to arms 28 carried by the arms of the wheel-folding lever C and a lJ-shaped member 29 having a web 30 located in the rear of the back and having forwardly-extending arms 31 connected by pivots 32 to the upper ends of the levers 23, said member 29 serving as a means for adjusting the back in either the-standing, halfreclining, or full-reclining position, according to desire. The arms 31 are provided at their lower edges with recesses, or notches, 33 which engage or rest on studs 34 with which the arms 15 rising from the rear bracket-members 12 to which are portion of the seat are equipped. The arms 31 of the member 29 are also provided with irregular shaped. slots 35 which receive studs 36 carried by the hinge-members 22 of the back. The slots 35 are provided with offsets 37, 38 and 39, which correspond respectively with the standing, half-reclining and full-reclining position of the back. It will be observed that the pin-and-slot connections 27 permit these adjustments to be made. It will also be observed that when the superstructure of the go-cart is being folded, the wheel-folding member C is thrown rearwardly, thereby forcing the links 25 rearwardly, and thus, through the medium of the levers drawing the backsupporting bail 29 forwardly and causing the back to be'folded forwardly with relation to the seat and running-gear frame. In this operation, the curved or beveled walls of the notches, or recesses, 33 ride on the studs 34, as will be understood by comparing Fig. 2 with Fig. 3. In the reverse operation, the arms of the back-supporting bail 29 ride on the studs 34 until the abrupt holders 40 of the recesses 33.engage the studs 34.

The mechanism F for locking the go-cart structure in the open position comprises a pair of locking-bars 41 having downwardly curved front ends connected by pivots 42 with the arms or links C some distance above the pivots 4; and guides 43carried by the rear portions of the side-members 7 of the running-gear frame, as shown in detail in Figs. 5 and 6. As shown in Fig. 5, the cross-member 10 of the running-gear frame has rearwardly turned ends 44 which are riveted to the side-bars of the running-gear frame, and the rear rivets 45 project in wardly beyond the rearwardly turned arms 44 and afford studs on which the guides 43 are mounted. Each guide 43 comprises a U-shaped clip having downturned arms 46 and a web, or top-member, 47. Each clip houses a spring 48 which bears againsta follower 49 which rests against the upper edge of the corresponding locking-bar 41. The stud 4'5 affords a locking-shoulder which coacts with a locking-notch 50 with which the lower edge of the locking-bar is provided.

The releasing means F comprises a U- shaped lever having a cross-member, or web, 51 and forwardly-extending arms 52 which project some distance in front of the studs 45 and are equipped with clips, or slides, 53 which engage the locking-bars 41 some distance in front of the guides 43. It will now be understood that when the rear end of the U-shaped lever F is depressed, as may be done by foot-pressure, the rear ends of the locking-bars F will be elevated, thereby disengaging the locking-notches 50 from the locking-studs-45, thus enabling the handle of the go-cart to be swung forwardly, in which imam operation the go-cart structure will be colla sed. In this operation, the'back will be fo ded forwardly upon the seat, and in the reverse operation, t e back will be elevated to a standing osit-ion.

The foregoing detailed description has been givenfor clearness of understanding only, and no undue limitations should be understood therefrom, but the appended claims should be construed 'as broadly as permissible in view of the prior art.
